My friend booked this hotel and we stayed here only 1 night.
This is the family running hotel, the father wasnt a service minder.

The hotel locates in a good location a walking distance to Duomo.

My partner and I arrived at the Arco hotel after a long day of traveling and walked to the hotel. When we arrived at 8.30pm the guy at reception informed us that we would be staying at another hotel tonight, which was just as good he said. His brother who also works for the hotel drove us to the other hotel about 5ish minutes away. Better he said, well I wasn't keen to go back to the Arco hotel. Our room smelt so bad of cigarette and luckily we could open a window to get air. The next morning we went to the Arco hotel and the brother picked us up. It is a bit better than where we got sent to, at least it doesn't smell like cigarette. The room and bathroom overall were really clean. My partner almost had an asthma attack from the amount of bleach that the floor was cleaned with. The family that run the hotel could a of been a bit nicer to guests. Even though it is only a 2 star hotel they are still running a business. The Father makes a great coffee in the morning too. Although he doesn't come across nice.

Good location, but noisy street and horrible staff. Head of reception does not speak english, very unfriendly man. Common spaces are dirty, lot of noise from the street.

DON'T stay in this hotel, it's horror staff and hotel too. Very poor hotel, very small rooms, very hight but the worst is staff, vary rude italian family, with 2 sons, one of them speaking a bit english. They are very agressive. For breakfast you can eat only one croissnet (from plastic - not fresh like "seven days croissant" and dring one cup coffee or juice. They are so so so RUDE and agressive!!! We decided to change hotel after one night, we wonna pay for this night by cash, but one of this guy Nicholas made transaction from my boyfriend credit card without our agree. He had number of card from web site reservation and put numbers to terminal and made this wit smile on face without our permission!!!!be carrefull to put your credit card number on budget site.
Realy don't go there, is realy very bad idea to reservate this hotel!!!
After we change hotel to Mozart hotel, completety diffrent standard, nice staff, talking in english great, wonderfull breakfast, beautifull room!
Think before you made reservation to ARCO HOTEL- IT'S HORROR!!!Dont go there!!!
